Cologne-based Energy-as-a-Service provider Einklang secures fresh funding in the millions for a battery-optimized power solution for commercial and industrial customers
Cologne, 23 February 2026 – The Cologne-based company Einklang, specialized in integrated energy solutions for Germany’s mid-sized businesses, has secured €2.2 million in funding. With this capital, Einklang plans to scale its battery-optimised electricity tariff solution for commercial and industrial customers and expand operations to 100 customer sites by 2026. The solution enables these businesses to reduce their electricity costs by 30 to 40 percent. The funding round was led by Vireo Ventures. Other investors include SI Ventures, Saxovent, Angel Invest, Heimatboost, and DnA Ventures.
Founders with a Proven Track Record
Einklang exemplifies the new generation of successful spin-offs from the energy startup ecosystem. The founders bring years of experience from building and scaling companies such as Voltfang (Aachen) and Impuls Energy (Cologne). This combination of hands-on industrial expertise and deep knowledge of algorithmic energy trading forms the foundation of Einklang’s technological approach.
Addressing Structural Challenges of the Energy Transition for mid-size companies
“We’re solving a central problem of the energy transition,” says Lucas Jonas, co-founder and CEO of Einklang. “While energy-intensive industries are granted relief through tailored regulations, mid-size companies continue to face high electricity prices. The issue isn’t renewable energy itself, but rather price volatility, high grid charges, consumption peaks, and a lack of flexibility. Our solution tackles exactly these problems.”
By integrating electricity procurement, storage, and consumption, Einklang enables companies to automatically source power when it’s inexpensive and renewable. This helps to reduce price volatility and peak loads, lower grid fees, and improve planning certainty. The solution is already in regular use at manufacturing and industrial customer sites. Depending on the starting situation, companies can cut their electricity costs by 30 to 40 percent. New sites can generally be transitioned to battery-optimised tariffs within three months.
Strong Team, Strong Vision
The decisive factor for our investment was the exceptionally strong team at Einklang, with its practical experience from previous ventures and industry expertise. Einklang has a clear vision of becoming a decentralized full-service provider for flexible energy systems in the mid-sized business sector. The current regulatory framework creates significant potential for integrated solutions combining battery storage, PV, dynamic tariffs, and intelligent control,“ says Felix Krause, Partner at Vireo Ventures.
Vision: Electricity in Harmony with Sun and Wind
“Only when consumption, storage, and procurement are intelligently coordinated can electricity become both affordable and predictable,” adds Lucas Jonas. “Our goal is to ensure that companies automatically use power when the sun shines or the wind blows – smartly and without any operational complexity.”
With this successful funding round, Einklang is sending a strong signal for a sustainable energy transition in the industrial Mittelstand. The company will now focus on further developing its technology platform and building strategic partnerships to establish flexible energy systems as the new standard for mid-sized businesses.
